When should repairs be made to front and rear headers?

Repairs to front and rear headers are typically warranted when there is significant structural deformation that compromises the integrity of the container. The standard threshold for initiating repairs often considers a depth of deformation greater than 35 mm. At this level, the risk of impact on the container's functionality and safety increases substantially. Such deformation can affect the ability of the headers to maintain their load-bearing capacity, potentially leading to further damage or failure during service.

In contrast, while deformation that is less than this threshold might not immediately necessitate repairs, it's important to monitor the condition closely. Cracks and deformation can indicate underlying issues, but not all cracks or minor deformations indicate that repairs are urgently needed. A depth greater than 35 mm serves as a clear and specific guideline for when actionable repairs should take place, ensuring the container's safety and effectiveness in transport.
